JOHN IJ- SAUCHEREAU, OF SPOKANE, WASHINGTON.

WATER-PUMP.

To all whom it may concern:

Be it known that 1, JOHN L. SAUOHEREAU, a citizen of the United States,residing at Spokane, in the county of Spokane and State of WVashington,have invented new and useful Improvements in VVater-Pumps, of which thefollowing is a specification.

My invention relates to an improved form of pump and has as itsprincipal obj set the provision of a pump having a maximum eiiiciency.

A second object of my invention is to provide an improved form mountingfor the piston of a pump of the revolving piston type.

A. third object resides in the particular arrangement and combination ofparts hereinafter described.

In the accompanying drawings :Figure 1 is a side elevation of a pumpembodying my improvements. Fig. 2 is a plan view of the pump shown inFig. 1. Fig. 3 is a sectional view taken on the line 33 of Fig. 2. Fig.4 is a horizontal section on the line 4t of Fig. 1. Fig. 5 is aperspective view of the piston showing details of my improved mountingarrangement. Fig. 6 is a detailed view of a portion of the apparatusshown in Fig. 3 drawn on an enlarged scale. Fig. 7 is a detail view of aportion of the apparatus shown in Fig. 1. Fig. 8 is an interior view ofone of the cylinder heads used in my pump.

Throughout the separate views the same part is designated by the samereference character.

Referring more particularly to the drawings, 1 indicates the cylinder ofmy pump which is mounted on suitable standards 2, the cylinder 1 beingin two parts separable along a horizontal line as indicated at 3. 4 and5 are the heads for the cvlindcr 1 and a shaft 10 is shown as passingthrough the cylinder and set at an angle to the axis thereof. Suitablestufling boxes 6 and 7 are provided where the shaft 10 passes throughthe cylinder heads 4- and 5, respectively, these stufling boxes beingset at an inclination to the base of the cylinder heads so as toproperly accommodate the shaft. Shaft 10 is shown as mounted in suitablebearings such as 8-8 which may be of any convenient type and at one endthe shaft 10 is connected by means of a reducing coupling 10 to theshaft extension 10 which has ri id therewith a pinion 36 Specificationof Letters Patent.

which meshes with a gear wheel 37 which tlIlVGS in turn a shaft 38. Theshaft 38 is provided with a crank and pitman connection with a smallreciprocating pump 29, the purpose of which will hereinafter appear. Thepump 29 may be of any convenient type, the details of this pump formmgno part of mv invention.

Referring more particularly to Figs. 3 and 4, it will be seen that theshaft 10 is divided into two sections, each of which is provided with aflaring flange such as 11. The flanges 11 make the same angle with theshaft 10 as does the inner face of the casing 1 so that the flanges runin contact with the inner face of the casing. The flanges 11 are boltedto the cone member 12 which is in the form of two cones set base to baseand which is divided into two parts by the piston or blade 14. It willappear that the two outside surfaces of the members 12 also have theproper inclination so as to run in contact with the inner faces of thecylinder head. Within the member 12 is a pin 13 which is set at rightangles to the shaft 10 and also at right anglcs to the blade or piston14. The pin 13 is attached to the two parts of the member 12 by means ofthe tapered keys 23. Now it will be seen that the piston 14: is providedwith a hub 15 which is bored to accommodate pin 13 and the bore of thehub 15 is tapered from both ends toward the middle to provide coneshaped interior surfaces. It will also be seen that the pin 13 tapers inthe opposite direction. As best shown in Fig. 6, two tapered rollerbearings 16 are mounted intermediate the hub 15 and the pin 13. Theindividual cones of the bear ings 16 are attached to gage rings such as16 at their larger ends and rings such as 17 are placed outside of thegage rings. Outside of the rings 17 are collars 18 which have threadedconnection with the pin 13 as shown at 19. The rings 18 are providedwith holes 21 by which they may be adjust" ed on the pin 13 and both therings 17 and 18 are provided with opposing grooves witlr in which aremounted balls such as 20. The cone member 12 is provided with platessuch as 22 and by removing these plates a spanner wrench may be insertedwhereby the cone bearings 16 may be adjusted so as to run properly inthe tapered bore of the hub 15, the wrench fitting the holes 21.

As shown in Fig. 5, the piston 14 is attached to rings 24- which are onopposite sides of the piston and which run in grooves such as 27 whichgrooves are turned on the inner faces of the heads iand 5, the rings 2stbeing flushed with the inner face of the heads when in position. Theoutside faces of the rings 2% are provided with pockets such as 26,clearly shown in Fig. 5, for the purpose of retaining a lubricant suchas water. H ow the grooves 27 are connected to the discharge of the pump29, previously mentioned, by the pipe 28, and the water forced into thegrooves 27 by the pump 29 is caught by the pocket 26 and distributedaround the grooves so as to lubricate the passage of the rings, and alsoserve to keep the piston in proper position. As clearly shown in Fig. l,the bottoms of the grooves 27 are turned out as shown at 27 so as topermit the liquid from the pump 29 to be evenly distributed around theentire circum ference of the grooves even when the rings are in runningosition.

In the operation of my novice it will be apparent that the cone 12 is incontact with the heads at and 5 at the points 30 and 31, respectively,and consequently forms a dam at these points even though moving, sinceit runs concentrically with the shaft 10. The blade let runsconcentrically with the rings 24 which are at an angle to the axis ofthe shaft 10. From this it follows that when the shaft is revolved theblade 14- is swung from side to side on the pin 13 as an axis. I haveprovided head a with an intake through pipe 32 and a discharge throughport 33, while the head 5 is provided with an intake through pipe 3 anda discharge through port 35. It will be understood that the inlet 32 ison an opposite side of the contact point 31 from the outlet 83 and thatthe inlet 34: is on an opposite side of the point 30 from the outlet 35.Consequently, when one half of the piston it passes by the inlet, thedirection of rotation being as shown by the arrow in Fig. 1, water willbe drawn in behind the piston and that before the first mentioned halfof the piston reaches the outlet, the other half of the piston will havepassed the inlet, thus inclosing a body of water within the pump, andwhen the first mentioned half of the piston passes the outlet this bodyof water is forced out under pressure owing to the continued reductionin space between the piston and the outlet. The operation just describedis repeated and is the same for both sets of inlets and outlets. It willbe understood that the pump 29 is adapted to pump against a higher headthan the main pump so that the flow of water will be inv-Iard around therings 24, thus insuringthat they will be thoroughly lubricated. It willalso be obvious that instead of turning out the groove 27 as at 27' toprovide passage for the water from pump 29 all around the groove 27,that I may lead the pipe 28 around the outside of the heads l and 5 andtap off from the pipe 28 into the groove 27 at various points.

It will be understood that while I have shown and described thepreferred form of my invention, that various modifications thereof maybe made without departing from the spirit thereof, and that parts of myinvention may be utilized without using 'the whole.

Having thus described my invention, what I claim is 1.
